Abstract
A method for producing a cutting head is specified. The latter is manufactured from a blank, which in turn is manufactured by means of extrusion. During extrusion, a number of coolant channels as well as a number of flutes are formed, wherein the coolant channels and the flutes are in each case formed helically during extrusion. After extrusion, the flutes have a pitch that is adjusted by grinding the flutes to a finished dimension. The method is particularly material-saving. A corresponding cutting head is moreover specified.
